APPARATUS FOR SEPARATING BODIES OF DIFFERENT SPECIFIC GRAVITIES.

SPECIFICATION forming part of Letters Patent No. 273,037, dated February 2'7, 1883.

Application filed December 9, 1882. (No model.)

To all whom 'it may concern:

Be it known that we, JACOB W. DECASTRO and TEILE HENRY M times, of the city, county, andState of New York, have invented a new and useful Improvement in Apparatus for Separating Bodies of Different Specific Gravities, of which the following is afnll,clea-r, and exact description, reference being had to the accompanying drawings.

Our invention relates to an improved apparatus for carrying out the process for which we made applicationon the 25th dayof August, 1882, in machines for carrying out processes similar to the one there described, in which a gradual retreatingoverliow of the liquid is requisite, wh ch shall, in the operation of the machine, retire gradually from the circumferences toward the center. I V

In the apparatus described in said application there was described a pivoted overflowpipe pivoted in the center of the apparatus In our present. apparatus the overflow passes directly through the basket itself.

()ur apparatus will be readily understood from the accompanying drawings, in which.-

Figure 1 represents asectional view through our basket, showing the tube-driving mechanism Fig. 2, a view of the discharge or overflowpipe; Fig. 3, an end view of the same; Fig. 4, a bottom view of the same; Fig. 5, a plan of the machine, showing the countershafts.

0 represents the centrifugal basket, which may be of any suitable construction. The liquid to be introduced into this basket may beintroduced through any suitable apparatus; but in the drawings shown it passes through the central tube, H, and then passes to me bottom of the basket through the pipe cc, Two pipes, D D project outwardly through: the lateral openings through the periphery of the basket, in which they should fit'reasonably tight. The position of the inner edge of these tubes determines the thickness of the material deposited within the basket. The

tion of this collar is determined by the lever F, supported on the fulcrum G. As the collar is raised it is evident that the inner edges of the tubes D D will be moved outwardly, and as the collar E is depressed the inner edges will be moved inwardly. The motion of the collar is determined through the lever F by means of the link I, having,at its lower end a screwthread, K', upon which the worm-wheel M turns as a nut. This wheel M is turned by the screw L, which screw is itself turned by the pulley when-thrown in connection with the clutch P. i The pulley O is driven from the pulley W on shaft S. \V represents the overflow connected with the casing B.

The operation of our apparatus can now be readily understood. The collar E being raised, so that the pipes D D project as far as possible, the liquid to be separated is allowed to fall-intothebasket. The basketbyits revolution causes the deposit of the solid particlesin aring on the outside of said basket, the liquid overflowing ihrough pipes D D". As this deposit continues the pipes D D are continually drawn inward by the revolution of the nutM, turning on the screw-thread K, until the hasket is filled up to its capacity. The deposited material may be removed in anysuitable way.

What we claim as our invention, and desire to secure by Letters Patent, is-- '1. The combination of a centrifugal basket with a tube or opening projecting through its periphery,said tube being made automatically movablefrom the periphery inward, substantially as described.

2. The combination of the basket bell-crank lever B, and adjusting-collar E, I substantially as described.
